The direction of electric field by the charge in and on the metal block will be along the direction line 5 as given in question.

<h3>How to determine electric field direction in a metal block?</h3>

The charge always remain on outer surface of metal and inside the metal block, the net electric field is zero. But due to dipole there is an electric field at the center of metal block i.e. at point R along direction line 1.

Now, to make make the net electric field zero at center, the electric field by the charge in and on the metal block must be equal in magnitude to that of electric field due to dipole at point R and in opposite direction to that of the net electric field at at R due to dipole.

The electric field by the charge in and on the metal block will be making 180° angle to the electric field due to dipole at point R.

Hence the direction of electric field by the charge in and on the metal block will be along the direction line 5 as given in question.

A 69-kg student sitting on a hardwood floor does not slide until pulled by a 260-N horizontal force. find coefficient of frictio

salantis [7]

Answer:

μ = 0.385

Explanation:

Given that,

The mass of the student, m = 69 Kg

The horizontal force applied, F = 260 N

The normal force acting on the body, weight = mg = 69g N

= 676.2 N

The coefficient of friction acting on a body is equal to the force acting on the body to the normal force acting on the body due to gravitation.

The formula for coefficient of friction,

μ = F / N

Substituting the values in the above equation,

μ = 260 N / 676.2 N

= 0.385

Hence, the coefficient of friction, μ = 0.385

A four-wheel-drive vehicle is transporting an injured hiker to the hospital from a point that is 30 km from the nearest point on

zepelin [54]

Answer:

$D=200\ km$

Explanation:

distance on terrain, $d_t=30\ km$

distance on the road, $d_r=70\ km$

speed on terrain, $v_t=30\ km.hr^{-1}$

speed on road, $v_r=130\ km.hr^{-1}$

<u>time taken on the terrain,</u>

$t_t=\frac{d_t}{v_t}$

$t_t=\frac{30}{30}$

$t_t=1\ hr$

<u>time taken to cover the distance on the road:</u>

$t_r=\frac{d_r}{v_r}$

$t_r=\frac{70}{130}$

$t_r=\frac{7}{13}\ hr$

<u>Now the distance covered on terrain in the total time:</u>

$D= v_r\times (t_r+t_t)$

$D= 130\times (\frac{7}{13}+1)$

$D=130\times \frac{20}{13}\$

$D=200\ km$

<em>is the distance the vehicle must target on the road to minimize the time taken in going off the road.</em>

fenix001 [56]

Answer:

1.it also hleps us to became doctors becuase without physics you can't be a doctor

2.physics needs to be steady whether you like it or not it helps you in life so everybody must study physics no matter is in Uganda USA and plenty more countries there must be physics to dare to be studied
